Do you have also Sony wide converter?
The Wide Conversion Lens DMW-GWC1 just arrived, a quick test on 14mm and 20mm pancake, mounts and appears to work identical on both. First thing you notice is how small and light this converter is, it's the same outside diameter as the 20mm pancake lens. The perspective on the 14mm is awesome, not much distortion of the verticals, this is going to be great for use on the SteadyCam.
The 55mm Marumi filters i have all fit perfectly into the inside of the wide adapter with just enough friction for it to stay in place, would not support a hood though without further mods.
Post some sample stills and video soon.
Any tests or questions please ask.
Specially for you, check the title of the topic, it is about Panasonic converters.
@John_Farragut: The Siocore 0.7x wide angle converter does provide a 72mm filter thread on its outside (and it's much cheaper than the Panasonic wide converter), see http://www.siolex.de/konverter/fuer-spiegellose-systemk/weitwinkel-konverter/siocore-37mm-52mm-0-7x-weitwinkel---makro-olympus-pen/a-87987952/
But be careful though to not strain your lens with too much additional weight. If you mount not only the converter but also additional filters, that may one day be too much for a pancake zoom to carry.
@Hallvalla: Mounting first a filter and then a converter in front of it might be a not-so-clever idea, if you think about how this changes the optical parameters of the setup (the distance from the converter to the lens).
JR.com(USA) has them.

@John_Farragut, I know right. I am sure there's could be a way to mount it on there if I try hard enough. Noktor 12mm is screwing up, I don't think I will sleep well paying $800 for the Oly 12mm f2. Can't win!
I want to buy to get a wider angle, but would love to use ND filter or hood. It always surprises me that these conversion lenses have no filter thread. Same with the Sony camcorder lenses. Had to buy Raynox to get filter thread for that.
